Human created chemicals can be “too good” at their job, remaining persistent and/or toxic in the environment, well beyond the life span of their commercial use. Read on to explore how DDT was found at depths up to 2500 m in the Arctic Ocean by a team from Stockholm University. Anna RobuckI am a third […]
Rachel Carson was right to focus her novel on the effects of DDT; DDT persists to this day in dolphins off the California coast in forms that are often not monitored by monitoring programs. Anna RobuckI am a third year PhD student at the University of Rhode Island Graduate School of Oceanography in the Lohmann […]
Chesapeake Bay osprey populations were at an all-time low in the 1970’s due in part to pesticides like DDT. Forty years later, organic pollutant concentrations in eggs and fledglings are on the decline and observations from 2011-2012 suggest there were no large scale effects of organic contaminants on osprey productivity. Kari St.LaurentI received a Ph.D. […]
Animals in early stages of development are particularly susceptible to harmful effects of toxic pollutants. For this reason, the transfer of toxic pollutants from mothers to their young has been the subject of intense research. In this study, researchers from California State investigated how non-mammalian species like sharks, skates, and rays pass toxic pollutants on […]
